From the merchant point of view, I can't see how you can get defrauded with a wire transfer: as far as I know, there is no chargeback / recall / etc. possible. Once the funds reach your account, they should stay here.
The person who provides the routing and account numbers to the merchant doesn't necessarily have to be the account holder, and then the authorities get involved and I assure you, they can compell you or your bank to return the fraudulent wire to the actual account holder.
The legal system will make sure the funds do not stay in your account.
As the other poster mentioned, you won't suffer chargebacks, but you _will_ find yourself on the receiving end of calls from the AML of your bank (if you're lucky), or your local authorities if you're less lucky. I am names on a clubs accounts for a local club and the terms we've signed up to are funds frozen for 6 months if we are _suspected_ of being involved even indirectly of laundering any money.
Have you ever dealt with fraud at any reasonable amount of scale? This is an absolutely _terrible_ idea.
